I both love and loathe Geography at the same time. I squirm at the irregularities – not the Slartibartfastian squiggly coastlines – but the way that people of differing cultures, languages and political or religious adherences refuse to occupy territory neatly, and deny being categorised properly. Actually, no, that’s just a joke. I love diversity, and migration, and long may culture continue to evolve. I find the differing mental geographies of people intriguing – such as the rift between the climate change science community and those few shrill shills resisting climate change science; for some reason often the very same people ardently opposed to the deployment of renewable energy. How to communicate across psychological boundaries remains an ongoing pursuit that can be quite involving and rewarding sometimes, as the entrenched antis diminish in number, because of defections based on facts and logic. One day, I sense, sense will prevail, and that feels good.

So I like divergence and richness in culture, and I like the progress in communicating science. What I don’t like is trying to map things where there is so much temporal flux. The constantly rearranging list of Membership of the European Union, for one good and pertinent example; the disputes over territory names, sovereignty and belonginess. When it comes to Energy, things get even more difficult to map, as much data is proprietary (legally bound to a private corporation) or a matter of national security (so secret, not even the actual governments know it); or mythical (data invented on a whim, or guessed at, or out of date). And then you get Views – the different views of different organisations about which category of whatever whichever parties or materials belong to. In my struggle to try to understand petroleum crude oil production figures, I realised that different organiations have different ways of grouping countries, and even have different countries in similar-sounding groups.

So I decided that as a first step towards eliminating categorisation overlaps or omissions, I should establish my own geography which was flexible enough to accommodate the Views of others, and permit me to compare their data more knowingly. Here are my first versions :-

2. Country Regional Comparison
I have compared the definitions of territorial regions between the following organisations and agencies : JODI (Joint Organisations Data Initiative), BP plc (the international company formerly known as British Petroleum), OPEC (the Organization of Petroleum Exporting Countries), EIA (United States of America, Department of Energy, Energy Information Administration), IEA (International Energy Agency of the OECD Organisation for Economic Co-operation and Development) and the United Nations (UN). Here it is as an Excel spreadsheet (.XLS). And here it is as a Comma-Delimited text file (.CSV).

There are some differences. Surprisingly few, in fact, if you only consider countries with significant oil production. I did find quite a lot of spelling mistakes, however, even in documentation that I assume was partially machine-generated.

The result is that I can be fairly confident that if I separate out data for China, Mexico, Israel and Turkey and a few other less significant countries when I compare data sources, any large divergence in numbers will have to be down to the different ways that people count oil rather than the way they categorise territories.

This is my first attempt to reconcile the 2015 global oil production data from five different publicly available sources : JODI Oil, BP, OPEC, EIA and IEA, and truth be told, it’s ugly.

I can feel I’m going to need to redo every step, just in case I made an error in assumption or copying figures into my spreadsheet(s).

I’m also going to need to contact each of the agencies for one reason or another, in particular to request a country-by-country full breakdown of the data, as it is impossible in some cases to compare the regional country groupings used by each agency.

In order to do this comparison, it has been necessary to read the “fine print” in the data reports and database information from the agencies, to try to understand how each of them treats each territory it holds data for, and which geographical region it assigns to which data for each country. A couple of notes here should show how complicated it can get : for example, BP considers Mexico to be a part of “OECD Americas” and “North America”, but OPEC considers it to be in “OECD Americas” and “Latin America”; the EIA consider Estonia to be a part of “Eurasia” in recent data downloads, whereas BP considers it a part of “OECD Europe” in the Statistical Review of World Energy 2016; and OPEC includes data from Indonesia in its total of OPEC oil production for 2015 in the Annual Statistical Bulletin 2016, but Indonesia only rejoined OPEC on 1st January 2016.

1. JODI Oil Data
I downloaded this data in late May 2016, and ran it through a C programme to group the country data roughly according to the BP schema.

2. Missing JODI Data
Where country data was missing in JODI, I filled in the gaps by pulling out the figures from the EIA Crude Oil (including Lease Condensate) data. I chose this data set because a comparison of figures between JODI Oil and EIA for the United States showed they were close. This I call “Adjusted JODI” data.

3. Regrouped Adjusted JODI Data
I re-grouped the Adjusted JODI data to match the regional groupings of the other data sets – essentially pulling “OECD Asia Pacific” and “Other Asia” data into the same group.

4. OPEC Annual Statistical Bulletin
I took the data for OPEC oil production from the OPEC ASB 2016 Table 3.5 and for the rest of the world from OPEC ASB 2016 Table 3.7. I then compared OPEC and JODI Oil data by subtracting the JODI data from the OPEC ASB data. Since some of the countries were not specifically named, and belonged to different regions in the JODI analysis, the results are not completely accurate. It was not possible to split “Eastern Europe and Eurasia” into “Europe” and “Eurasia” countries.

5. Adjusting OPEC ASB data for OPEC countries
The OPEC data for OPEC countries does not report Lease or Field Condensates in the main crude oil figures – these are lumped in with NGL figures, which also include NCF – non-conventional fossil fuels. The OPEC data for non-OPEC countries appears to include NCF in the main crude oil figures. The JODI Oil data do not appear to include NCF. So for the regions where there were significant NCF showing in the EIA data, I added these on to the JODI figures to permit a clearer comparison to the OPEC data.

6. IEA Oil Market Report (OMR)
I took the 2015 data from the International Energy Agency (IEA) OMR of 13 July 2016 and compared them to the Adjusted JODI data. The difference for the OPEC figure seemed very large, and this appeared to be because NCFs were included for the OPEC data, but not in the other figures. So I subtracted the OPEC NGLs figure from the IEA OPEC total, and instead added in the NGLs figure from the EIA data for the comparison with JODI.

8. BP Data
I compared the BP Statistical Review of World Energy 2016 page 8 for oil production in thousands of barrels per day with the JODI data. I needed to move some of the countries between regions for the comparison, but this was not possible as they were not explicitly mentioned in the BP data – splitting “Europe and Eurasia” into “OECD Europe”, “Eurasia” (Former Soviet Union or FSU) and “Other Europe”.

My main conclusion so far is that anybody basing analysis on any of these data sets should be very wary. Some of the numbers look suspect. Also, the total production of hydrocarbons may be larger than previously, but it’s an apples and oranges problem : NGLs are not the same as crude oil, and cannot give the same amount of refined oil products.

In my next post, I’m going to explain all the acronyms I haven’t explained this time, and delve further into regional geography.

Zeroes, man. Or as most computer scientists say, “It’s a null value problem.” Trying to tally the JODI Oil data with BP data, I encountered the “binary meaning of a zero” question – where you ask “is this really a zero value, or is it a missing value (or null) ?” Nulls are the bane of engineers and social scientists alike. Helpfully, JODI has provided a guide to trying to determine whether a zero is a null or a zero value, in the form of the download JODI-Oil monthly data availability by country (in Excel file) on the Data Downloads web page, but I found one or two problems when I looked into the actual data – where a data point is supposedly available, it is sometimes given as a zero. I also found that some of the totals given in the JODI Oil data were given as zeroes instead of proper values. I am going to report what I found to JODI, but in the meantime, I have improved my C programmes to read the JODI Oil data and produce reports similar to those found in the BP Statistical Review of World Energy.

This time, I have reproduced page 8 from the 2016 BP Stat Rev based on JODI data and then calculated the difference for each value between the two versions. I have used conditional formatting in Excel to create a spectrum of cell background colours to highlight where the two data sets diverge. It seems clear that data problems for North America were fixed in one or other of these two data sources in 2009, but data for the Middle East are still quite divergent. Most of the countries in the Middle East are in the OPEC group, and according to various documents, their figures for crude oil production do not include NGLs – Natural Gas Liquids (or Natural Gas Plant Liquids), so I thought this was possibly where some of the divergence came from. So as an experiment, I looked up the OPEC Annual Statistical Bulletin (ASB) for 2016 to get 2015 crude oil production data for OPEC countries from Table 3.6 “World crude oil production by country (1,000 b/d)” and found some agreement with the JODI Oil data. This was not a total surprise, as OPEC reports into the JODI group. JODI Oil however, is reporting significantly higher than OPEC for several key OPEC countries – so this will take some further investigation.

What this experiment confirms is that BP is probably reporting high for the Middle East because of the NGLs question. But the BP report is showing much higher values for crude oil production for the non-OPEC category as well, and only shows close agrement with JODI Oil for the European Union region and the OECD.

The NGLs question is hard to answer, because OPEC report NGLs for the OPEC group as a whole and not for each individual country. So now I have to go back to the EIA dataset for an independent data source to try to untangle this. I don’t know how independent any of these data sources are, though. They seem to rely on each others’ data reports in some cases, and their reporting cycles are staggered accordingly. OPEC has a table of monthly production from “secondary sources”, which presumably means companies or countries further upstream in oil production, which would also be reporting to JODI.

It looks like I have more to understand about oil production (and consumption) reporting before I can get on to world gas.

In my seemingly futile and interminable quest to reconcile the differences between the data provided by the JODI Oil organisation and BP as revealed in part by the annual BP Statistical Review of World Energy, I have moved on to looking at production (primary supply), found a problem as regards Africa, and had some confirmation that a major adjustment in how the data is collected happened in 2009.

First – the problem with Africa. The basket “Other Africa” for oil production is far less in the BP data than it is in the JODI Oil data – shown by negative figures in the comparison. For 2015, this is approximately 65% in scale (-3800 KBD) of the summed positive difference between the BP and JODI figures for the named countries (5884 KBD). This reminds me that there was a problem with the refined oil product consumption figures for “Other Africa” as well. Without a detailed breakdown of individual country accounts from BP it is almost impossible to know where these differences arise, it seems to me, or begin to understand why these differences are so large. Maybe I should just ask BP for a full country breakdown – if they’d ever deign to communicate this kind of information with me. Standing by my email Inbox right now… Could be here some time…

It is fairly clear from the comparison for North America that a major shift in understanding by either BP or JODI Oil took place in 2009, as the oil production data converge significantly for that year onwards. There was similar evidence of this in the refined oil products consumption data.

As with the consumption data, the production data for the Middle East region is strongly divergent between BP and JODI. I did read something potentially useful in the JODI Oil Manual, which I would recommend everyone interested in energy data to read. In the notes for Crude Oil, I read : “One critical issue is whether the volumes of NGL, lease or field condensates and oils extracted from bituminous minerals are included. All organisations exclude NGL from crude oil. If condensates are able to be excluded, it should be noted to the JODI organisation(s) of which the country/economy is a member. Most OPEC member countries exclude condensates.” Now, I guess, the struggle will be to find some data on condensates. Of which there are a variety of sources and nomenclature, be they light liquid hydrocarbons from oil and gas production or oil and gas refining/processing/cryoprocessing. There may be faultlines of comprehension and categorisation, such as about who considers NGPL or Natural Gas Plant Liquids from Natural Gas processing plants to be in the category of NGLs – Natural Gas Liquids, and therefore effectively in the bucket of Crude Oil.

I’m no closer to any answers on why BP oil data doesn’t align with JODI Oil data. And it looks like I’ve just opened a whole can of condensate wormy questions.

The first thing that struck me was that there are many items of data that are very similar between the BP and JODI Oil data; and yet there are also a good number that are significantly different – and the vast majority of these show BP reporting much higher oil consumption than JODI. This means that the definitions that BP and JODI are using for oil products consumption must correlate in many cases, when countries make their reports. But it also means that there are some understandings of oil consumption that BP has that do not have cognates in the JODI Oil reports.

The second thing that struck me was that each region in BP apart from North America is showing a total much higher than JODI Oil. Only some of the countries are specifically named in the BP report, and other countries are lumped into the bucket of “Other” within each region. Each “Other” figure is much higher in the BP report than in the JODI Oil data. Part of the reason is clearly going to be because some countries have not been reporting to JODI Oil, or not reporting reliably. For example, for South and Central America, JODI Oil data for Bermuda, Cuba, El Salvador, Haiti and Suriname are all zeroes; and JODI Oil data for Bolivia has zeroes for NOV2015 and DEC2015 (other months average at 63 KBD). But these could all be expected to be low oil products producers; so it is unclear to me where BP thinks consumption is occurring outside of the individually-named countries.

The “Other Africa” line is much higher in BP than in JODI, which looks dubious. I have not looked at this closely, but this might relate to countries such as Nigeria who produce and also consume a lot of oil.

It could be that in some cases the BP data is for all oil consumption – from national refineries and imports; whereas the JODI Oil data is for consumption from a nation’s own refinery. I would need to check this in more detail, but at first glance, the BP oil consumption data for the Middle East is much more divergent from the JODI Oil data than for other regions, and this does not make sense. I know that refinery product self-consumption is increasing in Middle East countries that are in strong economic development, but not all Middle East countries are experiencing increasing national demand, and I cannot imagine that oil products imports are so high in this region as to explain these differences between BP and JODI Oil data.

Another thing to note is that Commonwealth of Independent States (CIS) (formerly known as the “Former Soviet Union”) data divergence accounts for most of the data divergence in the “Europe & Eurasia” region; and that BP oil consumption data for the Russian Federation (which forms a part of CIS) is much higher than the data given to JODI.

I now have too many questions about how and from whom all this data is sourced, how categories of liquid hydrocarbons are delineated, and doubts about how anybody could check the reliability of any of this data. Without more information, I cannot analyse this data further; but maybe looking at oil consumption is not that illuminating. There appears to be a small and steady increase in annual oil demand and consumption over the recent period – this is indicated by both BP and JODI Oil data. The real issues for my analysis are whether oil production is capable of sustainably satisfying this demand-with-small-annual-increases, so my next step is to move to look at liquid hydrocarbons production data.

Previously, I was comparing data from the annual BP Statistical Review of World Energy with the annual averages of JODI Oil data, and when I cast my eye over a table of differences, it was easy to spot that something happened in 2009 – the data from the two sources jumped to more closely correlate. For some countries and product types, if it didn’t happen in 2009, it happened in 2010; but since then some data lines have begun to diverge again. Either somebody was lying prior to 2009 (and by “lying”, I mean, making errors in reporting on hydrocarbon refinery), or something changed in the definitions of the sub-categories of hydrocarbon products from petrorefineries. At this stage, I cannot tell if the corrections were done by BP or by JODI Oil, but the corrections show a step change. This intrigued me, so, here follow a few diagrams and some summary notes.

The example of North America is dominated by a correction in the data for the United States of America (whether the correction was in the JODI Oil data, or in the BP data) for the “Others” category. Since 2009, the data lines have been coming progressively closer, until it seems they are reporting from either the same sources, or using the same industry data to base their calculations on.

Data from South and Central America as a whole is rather random when compared between BP and JODI – however there is a clear correction in the category “Others” in 2009, and perhaps a further correction to both “Light distillates” and “Others” in 2011. Since then, the trend is for BP and JODI data to diverge.

The 2009 correction for the “Europe and Eurasia” region (an artefact) is mainly due to the big correction for the European Union in 2009 for “Light distillates” and “Others”. The data for CIS undergoes a smaller correction, and this is in 2010, for “Fuel oil” and “Others”.

The “Others” category is also adjusted for the Middle East in 2009.

There are minor corrections in the data for Africa in both 2009 and 2010, and recently a large divergence for “Middle distillates”.

Asia Pacific data is corrected for “Light distillates”, “Middle distillates” and “Others” in 2009, reflecting corrections in both China and Japan data.

Corrections in 2009 for OECD data are the main reason for the differences between BP and JODI to snap shut; whilst Non-OECD data still remains divergent.

Two of my concerns of the week are to try to understand the status and health of the global economy – which can be seen through the lens of overall consumption of hydrocarbons; and to see if there are changes happening in relative demand levels for the different kinds of hydrocarbons – as this could indicate a transition towards a lower carbon economy. The BP Stat Rev of June 2016 offers an interesting table on Page 13 – “Oil: Regional consumption – by product group”, which breaks down hydrocarbon demand into four main categories : Light distillates, Middle distillates, Fuel oil and Other. The “Other” category for BP includes LPG – Liquefied Petroleum Gases, a blend of mostly propane and butanes (carbon chain C3 and C4), which are gaseous and not liquid at normal room temperature and pressure – so strictly speaking aren’t actually oil. They also have different sources from various process units within petroleum refinery and Natural Gas processing plants. The “Other” category also includes refinery gas – mostly methane and ethane (carbon chain C1 and C2), and hydrogen (H2); and presumably fuel additives and improvers made from otherwise unwanted gubbins at the petrorefinery.

Not by coincidence, the JODI Oil database, in its Secondary data table, also offers a breakdown of hydrocarbon demand from refinery into categories almost analagous to the BP groupings – LPG, Gasoline, Naphtha, Kerosenes, Gas/Diesel oil, Fuel oil, and Other products; where LPG added to Other should be the same as BP’s “Other” category, Gasoline added to Naphtha should be equivalent to BP’s “Light distillates”; and Kerosenes added to Gas/Diesel oil should be analagous to BP’s “Middle distillates. So I set out to average the JODI Oil data, day-weighting the monthly data records, to see if I could replicate the BP Stat Rev Page 13.

Very few of the data points matched BP’s report. I suspect this is partly due to averaging issues – I expect BP has access to daily demand figures, (although I can’t be sure, and I don’t know their data sources); whereas the JODI Oil data is presented as monthly averages for daily demand. However, there are a lot of figures in the BP report that are high compared to the JODI Oil database. This can only partly be due to the fact that not all countries are reporting to JODI – four countries in the Commonwealth of Indepdendent States (CIS) – formerly known as “Former Soviet Union” – are not reporting, for example. I’m wondering if this over-reporting in the BP report might be due to differences in the way that stock transfers are handled – perhaps demand for refinery products that are intended for storage purposes rather than direct consumption is included in the BP data, but not in JODI – but at the moment I don’t have any relevant information with which to confirm or deny this concept.

Anyway, the data is very close between BP and JODI for the United States in recent years, and there are some other lines where there is some agreement (for example – Fuel oil in Japan, and Light distillates in China), so I am going to take this as an indication that I understand the JODI Oil data sufficiently well to be able to look at monthly refinery demand, refinery output and oil production for each region and hopefully reach some useful conclusions.

In the United States, almost predictably in that uniquely litigious culture, various lawsuits are accumulating with the large oil and gas companies as their targets, and Exxon is the latest defendant. It is a matter of political, social and environmental import to have the facts where there is suspected misleading of the public on matters of science. In this case, if proved, those misled would include shareholders in the company.

And it’s not just a question of global warming science here – Exxon’s alleged readiness to obscure basic physics and the implications of carbon loading of the atmosphere from fossil fuel burning may have also resulted in an obscuring of the scientific realities underlying their own corporate viability.

You see, Exxon’s business interests rely on their continued ability to find and dig up oil and gas. Now last year was a difficult one, as depressed crude oil and Natural Gas commodity prices put some of Exxon’s resources “off-books”, so their reserves replacement – topping up their bankable assets – was only 67% of their previous end-of-year. It could be easy to connect the dots on this one – some of the gas they could pump is just too costly right now to get to. But what if Exxon are finally meeting another kind of Nemesis – of their own making – because they’re working on faulty geophysical data, which they produced themselves ?

So, let’s start where I did, with Chapter Eight “Basin stratigraphy” of the reference book “Basin Analysis” by Philip A. Allen and John R. Allen, 3rd edition, published by Wiley Blackwell, ISBN 978-0470673768.

The chapter introduces many important concepts regarding how sedimentary basins formed in deep Earth time – sediments of organic matter that have in some cases become reservoirs of fossil fuels. It talks about how strata get laid down – the science of “process stratigraphy”. Much of the logic relies on the phenomenon of the rising and falling of sea level relative to land masses over geological cycles, correlating with significant swings in climate. The book mentions early work by Exxon scientists : “Using seismic reflection results, a team of geologists and biostratigraphers from Exxon constructed a chart of relative sea level through time (Vail et al., (1997b), updated and improved by Haq et al. (1987, 1988)).” The chapter goes on to critique one important working assumption of that original work – that all sedimentary similarities must be an indicator of synchronicity – that is, that they happened at the same time. The text goes on to read, “In summary, we follow Carter (1998) in believing that the Haq et al. (1997) curve is a ‘noisy’ amalgam of a wide range of local sea-level signals, and should not be used as a global benchmark…its use as a chronostratigraphic tool by assuming a priori that a certain stratigraphic boundary has a globally synchronous and precise age, which it is therefore safe to extrapolate into a basin with poor age control, is hazardous.”

Why is this important ? Because all of the understanding of petroleum geophysics relies on the stratigraphic charts drawn up by these scientists. And yet, even at their inception, there was corporate “confidentiality” invoked. According to a paper from Anthony Hallam, Annual Review of Earth and Planetary Sciences, 1984, 12: 205-243 : “Most important, details of the evidence supporting the eustatic claims of the Exxon group (Vail et al 1977) are not published, and hence their claims cannot be checked directly”. What ? A data set relied on not only by everybody in the fossil fuel energy industry, but also all geologists and even climate change scientists, has a fault line in the evidence ? Why would Exxon want to obscure the origin of this data ? Did they need to keep quiet about their stratigraphy science because it revealed too much about climate change ? Are there problems with the science, but that even they didn’t find out ? And is there then the possibility that they have relied too much on faulty 40 year old research in fossil fuel exploration and discovery ?

Exxon might be starting to be more transparent – as this set of charts from 2010 reveals, “A Compilation of Phanerozoic Sea-Level Change, Coastal Onlaps and Recommended Sequence Designations”, Snedden and Liu, 2010, AAPG Search and Discovery, in which the text includes, “The magnitudes of sea-level change in this chart follow the estimation of Haq and Schutter (2008) and Hardenbol et al. (1998). However, there is little consensus on the range of sea-level changes, though most believe that the sea-level position during most of the Phanerozoic was within +/- 100 meters of the present-day level.”

To me, it remains an intriguing possibility that the whole oil and gas industry has been working with incomplete or misaligned data, in which case, can we really believe that there are another four or five good decades of good quality fossil fuels to exploit ?

I have had the great fortune to meet another student of the Non-Science of Economics who believes most strongly that Energy is only a sub-sector of the Holy Economy, instead of one of its foundations, and doesn’t understand why issues with the flow of commodities (which include energy resources) into the system is critical to the survival of the global economy, and that the growth in the Services Industries and Knowledge Economy cannot compensate for the depletion of freshwater, fossil fuels and other raw resources.

This person believes in Technology, as if it can fly by itself, without seeming to understand how Technological Innovation is really advanced by state investment – a democracy of focus. This otherwise intelligent learner has also failed to grasp, apparently, that the only way that the Economy can grow in future is through investment in things with real value, such as Energy, especially where this investment is essential owing to decades of under-investment precipitated by privatisation – such as in Energy – investment in both networks of grids or pipes, and raw resources. And this from somebody who understands that developing countries are being held back by land grab and natural resource privatisation – for example ground water; and that there is no more money to be made from property investment, as the market has boomed and blown.

How to burst these over-expanded false value bubbles in the mind ? When I try to talk about the depletion of natural resources, and planetary boundaries, people often break eye contact and stare vacantly out of the nearest window, or accept the facts, but don’t see the significance of them. Now this may be because I’m not the best of communicators, or it may be due to the heavy weight of propaganda leading to belief in the Magical Unrealism always taught in Economics and at Business Schools.

Whatever. This is where I’m stuck in trying to design a way to talk about the necessity of energy transition – the move from digging up minerals to catching the wind, sunlight and recycling gases. If I say, “Look, ladies and laddies, fossil fuels are depleting”, the audience will respond with “where there’s a drill, there’s a way”. As if somehow the free market (not that a free market actually exists), will somehow step up and provide new production and new resources, conjuring them from somewhere.

What are arguments that connect the dots for people ? How to demonstrate the potential for a real peak in oil, gas, coal and uranium production ? I think I need to start with a basic flow analysis. On the one side of the commodity delivery pipeline, major discoveries have decreased, and the costs of discovery have increased. The hidden underbelly of this is that tapping into reservoirs and seams has a timeline to depletion – the point at which the richness of the seam is degraded significantly, and the initial pressure in the well or reservoir is reduced to unexploitable levels – regardless of the technology deployed. On the other end of the commodities pipeline is the measure of consumption – and most authorities agree that the demand for energy will remain strong. All these factors add up to a time-limited game.

Oh, you can choose to believe that everything will continue as it always seems to have. But the Golden Age of Plenty is drawing to a close, my friend.

I fully expect the British Prime Minister, David Cameron, will be more than modicum concerned about public opinion as the full toll of damage to property, businesses, farmland and the loss of life in Cumbria of the December 2015 floods becomes clear. The flooding in the Somerset Levels in the winter of 2013/2014 led to strong public criticism of the government’s management of and investment in flood defences.

The flood defences that were improved in Cumbria after the rainstorm disaster of 2009 were in some cases completely ineffective against the 2015 deluge. It appears that the high water mark at some places in Cumbria was higher in the 2015 floods than ever recorded previously, but that cannot be used as David Cameron’s get-out-of-jail-free clause. These higher flood levels should have been anticipated as a possibility.

However, the real problem is not the height of flooding, but the short recurrence time. Flood defences are designed in a way that admits to a sort of compromise calculus. Measurements from previous floods are used to calculate the likelihood of water levels breaching a particular height within a number of years – for example, a 1-in-20 year flood, or a 1-in-200 year flood. The reinforced flood defences in Cumbria were designed to hold back what was calculated to be something like a 1-in-100 year flood. It could be expected that if within that 100 years, other serious but not overwhelming flooding took place, there would be time for adaptation and restructuring of the defences. However, it has taken less than 10 years for a 1-in-100 year event to recur, and so no adaptation has been possible.

This should suggest to us two possibilities : either the Environment Agency is going about flood defences the wrong way; or the odds for the 1-in-100 year flood should be reset at 1-in-10-or-so years – in other words, the severity profile of flooding is becoming worse – stronger flooding is more frequent – which implies acceptance of climate change.

The anti-science wing of the Conservative Party were quick to construct a campaign against the Environment Agency in the South West of England in early 2014 – distracting people from asking the climate change question. But this time, I think people might be persuaded that they need to consider climate change as being a factor.

Placing the blame for mismanagement of the Somerset Levels at the door of the Environment Agency saved David Cameron’s skin in 2014, but I don’t think he can use that device a second time. People in Cockermouth are apparently in disbelief about the 2015 flooding. They have barely had time to re-establish their homes and lives before Christmas has been cancelled again for another year.

Will the Prime Minister admit to the nation that climate change is potentially a factor in this 2015 waterborne disaster ?

I remember watching in in credulity as the BBC showed the restoration of Cockermouth back in 2010 – it was either Songs of Praise or Countryfile – I forget which. The BBC were trying to portray a town getting back to normal. I remember asking myself – but what if climate change makes this happen again ? What then ? Will the BBC still be mollifying its viewers, lulling them back into a false sense of security about the risks of severe climate change ? What if there is no “normal” to get back to any more ? Is this partly why the Meteorological Office has decided to name winter storms ?

Can future climate-altered floods be escaped – or are the people of Britain to remain defenceless ?

For example, the report states in Section 3.40 that : “…measures to protect and diversify sources of [energy] supply will become increasingly important, including the new Southern Corridor pipeline, US liquid natural gas (LNG) exports, further supplies of Australian LNG, and increased supply from Norway and North Africa.”

I have already addressed my recommendation that the writers of this report should be more careful to distinguish between Liquefied Natural Gas (LNG) which is a methane-rich product that can substitute for Natural Gas; and Natural Gas Liquids (NGLs) which is a methane-poor product that cannot substitute for Natural Gas.

However, assuming that the writers of the report are talking about cryogenically stored and transported Natural Gas-sourced energy gases, there is a problem in assuming that the United States will be exporting any large amounts of LNG to Europe any time soon. In fact, there are several problems.

Just because the business and political press have been touting the exciting prospect of US LNG exports, doesn’t mean that the data backs up this meme.

All of which adds up to a puzzled look on my face. How can the British Government reasonably expect the commencement of significant quantities of American LNG exports to arrive in the UK ? The only reason they believe this is because there has been American propaganda, promulgated through media of all kinds, for the last five or so years, to convince the world that the USA can achieve greater energy independence through the “explosion” in shale gas production.

It’s a story told by many successive US Governments – that the US can achieve greater energy independence, but the reality is very, very different.

The UK Government should not believe any narrative of this nature, in my view, nor include it in national security analyses.

She writes, “The ambit claims know no bounds. Who else would ask for $89,000,000,000,000? If the evil “more developed” nations pay for their carbon sins, the bill for those 1.3 billion people works out at $70,000 per person by 2030 (babies included).”

“The global economy will require substantial investments in infrastructure as the population and the middle class grow. An estimated US$89 trillion of infrastructure investment will be required through 2030, based on data from the International Energy Agency (IEA), the Organisation for Economic Co-operation and Development (OECD), and analysis for the Commission (see Figure 1). This is chiefly investment in energy and cities. This estimate for the required investment is before accounting for actions to combat climate change.”

That’s before accounting for actions to combat climate change, Ms Nova. Before. I know it’s probably clanging against your internal cognitive fences, but the fact is, the world needs to spend a heap of capital in the next 20 to 30 years reviving, replacing and renewing energy systems infrastructure. That spending has to happen regardless of whether it’s low carbon spending.

And let’s read the note on Figure 1 more carefully :-

“INCLUDING OPERATING EXPENDITURES WOULD MAKE A LOW-CARBON TRANSITION EVEN MORE FAVOURABLE LEADING TO A FURTHER REDUCTION OF US$5 TRILLION, FOR OVERALL POTENTIAL SAVINGS OF US$1 TRILLION”

So, Jo Nova, the world will actually be better off if it decides to make all new energy expenditure low carbon.

I was to join industrial developers and academic researchers at the Department of Energy and Climate Change (DECC) in a meeting of the “Green Hydrogen Standard Working Group”.

The date was 12th June 2015. The weather was sunny and hot and merited a fine Italian lemonade, fizzing with carbon dioxide. The venue was an air-conditioned grey bunker, but it wasn’t an unfriendly dungeon, particularly as I already knew about half the people in the room.

The subject of the get-together was Green Hydrogen, and the work of the group is to formulate a policy for a Green Hydrogen standard, navigating a number of issues, including the intersection with other policy, and drawing in a very wide range of chemical engineers in the private sector.

My reputation for not putting up with any piffle clearly preceded me, as somebody at the meeting said he expected I would be quite critical. I said that I would not be saying anything, but that I would be listening carefully. Having said I wouldn’t speak, I must admit I laughed at all the right places in the discussion, and wrote copious notes, and participated frequently in the way of non-verbal communication, so as usual, I was very present. At the end I was asked for my opinion about the group’s work and I was politely congratulational on progress.

So, good. I behaved myself. And I got invited back for the next meeting. But what was it all about ?

Most of what it is necessary to communicate is that at the current time, most hydrogen production is either accidental output from the chemical industry, or made from fossil fuels – the main two being coal and Natural Gas.

Hydrogen is used extensively in the petroleum refinery industry, but there are bold plans to bring hydrogen to transport mobility through a variety of applications, for example, hydrogen for fuel cell vehicles.

Clearly, the Green Hydrogen standard has to be such that it lowers the bar on carbon dioxide (CO2) emissions – and it could turn out that the consensus converges on any technologies that have a net CO2 emissions profile lower than steam methane reforming (SMR), or the steam reforming of methane (SRM), of Natural Gas.

[ It’s at this very moment that I need to point out the “acronym conflict” in the use of “SMR” – which is confusingly being also used for “Small Modular Reactors” of the nuclear fission kind. In the context of what I am writing here, though, it is used in the context of turning methane into syngas – a product high in hydrogen content. ]

Some numbers about Carbon Capture and Storage (CCS) used in the manufacture of hydrogen were presented in the meeting, including the impact this would have on CO2 emissions, and these were very intriguing.

I had some good and useful conversations with people before and after the meeting, and left thinking that this process is going to be very useful to engage with – a kind of dragnet pulling key players into low carbon gas production.

Here follow my notes from the meeting. They are, of course, not to be taken verbatim. I have permission to recount aspects of the discussion, in gist, as it was an industrial liaison group, not an internal DECC meeting. However, I should not say who said what, or which companies or organisations they are working with or for.

The British Government do not have an energy policy. They may think they have one, and they may regularly tell us that they have one, but in reality, they don’t. There are a number of elements of regulatory work and market intervention that they are engaged with, but none of these by itself is significant enough to count as a policy for energy. Moreover, all of these elements taken together do not add up to energy security, energy efficiency, decarbonisation and affordable energy.

What it takes to have an energy policy is a clear understanding of what is a realistic strategy for reinvestment in energy after the dry years of privatisation, and a focus on energy efficiency, and getting sufficient low carbon energy built to meet the Carbon Budget on time. Current British Government ambitions on energy are not realistic, will not attract sufficient investment, will not promote increased energy efficiency and will not achieve the right scale and speed of decarbonisation.

I’m going to break down my critique into a series of small chunks. The first one is a quick look at the numbers and outcomes arising from the British Government’s obsessive promotion of nuclear power, a fantasy science fiction that is out of reach, not least because the industry is dog-tired and motheaten.

An underlying issue not much aired is that increased gas infrastructure is necessary not just to improve competition in the energy markets – it is also to compensate for Peak Natural Gas in the North Sea – something many commentators regularly strive to deny. The new Conservative Government policy on energy is not fit to meet this challenge. The new Secretary of State has gone public about the UK Government’s continued commitment to the exploitation of shale gas – a resource that even her own experts can tell her is unlikely to produce more than a footnote to annual gas supplies for several decades. In addition, should David Cameron be forced to usher in a Referendum on Europe, and the voters petulantly pull out of the Europe project, Britain’s control over Natural Gas imports is likely to suffer, either because of the failure of the “Energy Union” in markets and infrastructure, or because of cost perturbations.

Amber Rudd MP is sitting on a mountain of trouble, undergirded by energy policy vapourware : the promotion of shale gas is not going to solve Britain’s gas import surge; the devotion to new nuclear power is not going to bring new atomic electrons to the grid for decades, and the UK Continental Shelf is going to be expensive for the Treasury to incentivise to mine. What Amber needs is a proper energy policy, based on focused support for low carbon technologies, such as wind power, solar power and Renewable Gas to back up renewable electricity when the sun is not shining and wind is not blowing.

So, this is the second slide from my presentation at Birkbeck, University of London, last week.

When making an argument, it is best to start from consensus and well-accredited data, so I started with government analysis of the energy sector of the economy in the United Kingdom. Production of Natural Gas in the UK is declining, and imports are rising.

I did not go into much detail about this chart, but there is a wealth of analysis out there that I would recommend people check out.

Despite continued investment in oil and gas, North Sea production is declining, and it is generally accepted that this basin or province as a whole is depleting – that is – “running out”.

The summary concluded with the estimate of remaining recoverable hydrocarbons from the UK Continental Shelf (offshore) resources would be between 11.1 and 21 billion barrels of oil equivalent (bboe).

Other data in the report showed estimates of cumuluative and annual oil production :-

Another source of estimates on remaining oil and gas resources, reserves and yet-to-find potential is from the Wood Review of 2014 :-

So it’s clear that British oil and gas production is in decline, and that also, reserves and resources to exploit are depleting. The Wood Review made several recommendations to pump up production, and maximise the total recoverable quantities. Some interpreted this as an indication that good times were ahead. However, increased production in the near future is only going to deplete these resources faster.

“The North sea is a very mature oil and gas province and it will inevitably go through a decline. It peaked in 1999 at around 2.9 millions barrels per day and our projections are that it will be half a million barrels in 2035”.

There are many ways to make a living, but there appear to be zero careers in plainspeaking.

I mean, who could I justify working with, or for ? And would any of them be prepared to accept me speaking my mind ?

Much of what I’ve been saying over the last ten years has been along the lines of “that will never work”, but people generally don’t get consulted or hired for picking holes in an organisation’s pet projects or business models.

Could I imagine myself taking on a role in the British Government ? Short answer : no.

The slightly longer answer : The British Government Department of Energy and Climate Change (DECC) ? No, they’re still hooked on the failed technology of nuclear power, the stupendously expensive and out-of-reach Carbon Capture and Storage (CCS), and the mythical beast of shale gas. OK, so they have a regular “coffee club” about Green Hydrogen (whatever that turns out to be according to their collective ruminations), and they’ve commissioned reports on synthetic methane, but I just couldn’t imagine they’re ever going to work up a serious plan on Renewable Gas. The British Government Department for Transport ? No, they still haven’t adopted a clear vision of the transition of the transport sector to low carbon energy. They’re still chipping away at things instead of coming up with a strategy.

Could I imagine myself taking on a role with a British oil and gas multinational ? Short and very terse and emphatic answer : no.

The extended answer : The oil and gas companies have had generous support and understanding from the world’s governments, and are respected and acclaimed. Yet they are in denial about “unburnable carbon” assets, and have dismissed the need for Energy Change that is the outcome of Peak Oil (whether on the supply or the demand side). Sneakily, they have also played both sides on Climate Change. Several major oil and gas companies have funded or in other ways supported Climate Change science denial. Additionally, the policy recommendations coming from the oil and gas companies are what I call a “delayer’s game”. For example, BP continues to recommend the adoption of a strong price on carbon, yet they know this would be politically unpalatable and take decades (if ever) to bring into effect. Shell continues to argue for extensive public subsidy support for Carbon Capture and Storage (CCS), knowing this would involve such huge sums of money, so it’s never going to happen, at least not for several decades. How on Earth could I work on any project with these corporations unless they adopt, from the centre, a genuine plan for transition out of fossil fuels ? I’m willing to accept that transition necessitates the continued use of Natural Gas and some petroleum for some decades, but BP and Royal Dutch Shell do need to have an actual plan for a transition to Renewable Gas and renewable power, otherwise I would be compromising everything I know by working with them.

Could I imagine myself taking on a role with a large engineering firm, such as Siemens, GE, or Alstom, taking part in a project on manufactured low carbon gas ? I suppose so. I mean, I’ve done an IT project with Siemens before. However, they would need to demonstrate that they are driving for a Renewable Gas transition before I could join a gas project with them. They might not want to be so bold and up-front about it, because they could risk the wrath of the oil and gas companies, whose business model would be destroyed by engineered gas and fuel solutions.

Could I imagine myself building fuel cells, or designing methanation catalysts, or improving hydrogen production, biocoke/biocoal manufacture or carbon dioxide capture from the oceans… with a university project ? Yes, but the research would need to be funded by companies (because all applied academic research is funded by companies) with a clear picture on Energy Change and their own published strategy on transition out of fossil fuels.

Could I imagine myself working on rolling out gas cars, buses and trucks ? Yes. The transition of the transport sector is the most difficult problem in Energy Change. However, apart from projects that are jumping straight to new vehicles running entirely on Hydrogen or Natural Gas, the good options for transition involve converting existing diesel engine vehicles to running mostly on Natural Gas, such as “dual fuel”, still needing roughly 20% of liquid diesel fuel for ignition purposes. So I would need to be involved with a project that aims to supply biodiesel, and have a plan to transition from Natural Gas to Renewable Gas.

Could I imagine myself working with a team that has extensive computing capabilities to model carbon dioxide recycling in power generation plant ? Yes.

Could I imagine myself modelling the use of hydrogen in petroleum refinery, and making technological recommendations for the oil and gas industry to manufacture Renewable Hydrogen ? Possibly. But I would need to be clear that I’m doing it to enable Energy Change, and not to prop up the fossil fuel paradigm – a game that is actually already bust and needs helping towards transition.

Could I imagine myself continuing to research the growth in Renewable Gas – both Renewable Hydrogen and Renewable Methane – in various countries and sectors ? Possibly. It’s my kind of fun, talking to engineers.

But whatever future work I consider myself doing, repeatedly I come up against this problem – whoever asked me to work with them would need to be aware that I do not tolerate non-solutions. I will continue to say what doesn’t work, and what cannot work.

If people want to pay me to tell them that what they’re doing isn’t working, and won’t work, then fine, I’ll take the role.

I’d much rather stay positive, though, and forge a role where I can promote the things that do work, can work and will work.

The project that I’m suitable for doesn’t exist yet, I feel. I’m probably going to continue in one way or another in research, and after that, since I cannot see a role that I could fit easily or ethically, I can see I’m going to have to write my own job description.

Last week, on the invitation of Dr Paul Elsner at Birkbeck, University of London, I gave a brief address of my research so far into Renewable Gas to this year’s Energy and Climate Change class, and asked and answered lots of questions before demolishing the mythical expert/student hierarchy paradigm – another incarnation of the “information deficit model”, perhaps – and proposed everyone work in breakout groups on how a transition from fossil fuel gas to Renewable Gas could be done.

A presentation of information was important before discussing strategies, as we had to cover ground from very disparate disciplines such as chemical process engineering, the petroleum industry, energy statistics, and energy technologies, to make sure everybody had a foundational framework. I tried to condense the engineering into just a few slides, following the general concept of UML – Unified Modelling Language – keeping everything really simple – especially as processing, or work flow (workflow) concepts can be hard to describe in words, so diagrams can really help get round the inevitable terminology confusions.

But before I dropped the class right into chemical engineering, I thought a good place to start would be in numbers, and in particular the relative contributions to energy in the United Kingdom from gas and electricity. Hence the first slide.

The first key point to notice is that most heat demand in the UK in winter is still provided by Natural Gas, whether Natural Gas in home boilers, or electricity generated using Natural Gas.

The second is that heat demand in energy terms is much larger than power demand in the cold months, and much larger than both power and heat demand in the warm months.

The third is that power demand when viewed on annual basis seems pretty regular (despite the finer grain view having issues with twice-daily peaks and weekday demand being much higher than weekends).

The reflection I gave was that it would make no sense to attempt to provide all that deep winter heat demand with electricity, as the UK would need an enormous amount of extra power generation, and in addition, much of this capacity would do nothing for most of the rest of the year.

The point I didn’t make was that nuclear power currently provides – according to official figures – less than 20% of UK electricity, however, this works out as only 7.48% of total UK primary energy demand (DUKES, 2014, Table 1.1.1, Mtoe basis). The contribution to total national primary energy demand from Natural Gas by contrast is 35.31%. The generation from nuclear power plants has been falling unevenly, and the plan to replace nuclear reactors that have reached their end of life is not going smoothly. The UK Government Department of Energy and Climate Change have been pushing for new nuclear power, and project that all heating will convert to electricity, and that nuclear power will provide for much of this (75 GW by 2050). But if their plan relies on nuclear power, and nuclear power development is unreliable, it is hard to imagine that it will succeed.

In the last couple of years I have researched and written a book about the technologies and systems of Renewable Gas – gas energy fuels that are low in net carbon dioxide emissions. From what I have learned so far, it seems that another energy world is possible, and that the transition is already happening. The forces that are shaping this change are not just climate or environmental policy, or concerns about energy security. Renewable Gas is inevitable because of a range of geological, economic and industrial reasons.

I didn’t train as a chemist or chemical process engineer, and I haven’t had a background in the fossil fuel energy industry, so I’ve had to look at a number of very basic areas of engineering, for example, the distillation and fractionation of crude petroleum oil, petroleum refinery, gas processing, and the thermodynamics of gas chemistry in industrial-scale reactors. Why did I need to look at the fossil fuel industry and the petrochemical industry when I was researching Renewable Gas ? Because that’s where a lot of the change can come from. Renewable Gas is partly about biogas, but it’s also about industrial gas processes, and a lot of them are used in the petrorefinery and chemicals sectors.

In addition, I researched energy system technologies. Whilst assessing the potential for efficiency gains in energy systems through the use of Renewable Electricity and Renewable Gas, I rekindled an interest in fuel cells. For the first time in a long time, I began to want to build something – a solid oxide fuel cell which switches mode to an electrolysis unit that produces hydrogen from water. Whether I ever get to do that is still a question, but it shows how involved I’m feeling that I want to roll up my sleeves and get my hands dirty.

Even though I have covered a lot of ground, I feel I’m only just getting started, as there is a lot more that I need to research and document. At the same time, I feel that I don’t have enough data, and that it will be hard to get the data I need, partly because of proprietary issues, where energy and engineering companies are protective of developments, particularly as regards actual numbers. Merely being a university researcher is probably not going to be sufficient. I would probably need to be an official within a government agency, or an industry institute, in order to be permitted to reach in to more detail about the potential for Renewable Gas. But there are problems with these possible avenues.

You see, having done the research I have conducted so far, I am even more scornful of government energy policy than I was previously, especially because of industrial tampering. In addition, I am even more scathing about the energy industry “playing both sides” on climate change. Even though there are some smart and competent people in them, the governments do not appear to be intelligent enough to see through expensive diversions in technology or unworkable proposals for economic tweaking. These non-solutions are embraced and promoted by the energy industry, and make progress difficult. No, carbon dioxide emissions taxation or pricing, or a market in carbon, are not going to make the kind of changes we need on climate change; and in addition they are going to be extremely difficult and slow to implement. No, Carbon Capture and Storage, or CCS, is never going to become relatively affordable in any economic scenario. No, nuclear power is too cumbersome, slow and dodgy – a technical term – to ever make a genuine impact on the total of carbon emissons. No, it’s not energy users who need to reduce their consumption of energy, it’s the energy companies who need to reduce the levels of fossil fuels they utilise in the energy they sell. No, unconventional fossil fuels, such as shale gas, are not the answer to high emissions from coal. No, biofuels added to petrofuels for vehicles won’t stem total vehicle emissions without reducing fuel consumption and limiting the number of vehicles in use.

I think that the fossil fuel companies know these proposals cannot bring about significant change, which is precisely why they lobby for them. They used to deny climate change outright, because it spelled the end of their industry. Now they promote scepticism about the risks of climate change, whilst at the same time putting their name to things that can’t work to suppress major amounts of emissions. This is a delayer’s game.

Because I find the UK Government energy and climate policy ridiculous on many counts, I doubt they will ever want me to lead with Renewable Gas on one of their projects. And because I think the energy industry needs to accept and admit that they need to undergo a major change, and yet they spend most of their public relations euros telling the world they don’t need to, and that other people need to make change instead, I doubt the energy industry will ever invite me to consult with them on how to make the Energy Transition.

I suppose there is an outside chance that the major engineering firms might work with me, after all, I have been an engineer, and many of these companies are already working in the Renewable Gas field, although they’re normally “third party” players for the most part – providing engineering solutions to energy companies.

Because I’ve had to drag myself through the equivalent of a “petro degree”, learning about the geology and chemistry of oil and gas, I can see more clearly than before that the fossil fuel industry contains within it the seeds of positive change, with its use of technologies appropriate for manufacturing low carbon “surface gas”. I have learned that Renewable Gas would be a logical progression for the oil and gas industry, and also essential to rein in their own carbon emissions from processing cheaper crude oils. If they weren’t so busy telling governments how to tamper with energy markets, pushing the blame for emissions on others, and begging for subsidies for CCS projects, they could instead be planning for a future where they get to stay in business.

The oil and gas companies, especially the vertically integrated tranche, could become producers and retailers of low carbon gas, and take part in a programme for decentralised and efficient energy provision, and maintain their valued contribution to society. At the moment, however, they’re still stuck in the 20th Century.

I’m a positive person, so I’m not going to dwell too much on how stuck-in-the-fossilised-mud the governments and petroindustry are. What I’m aiming to do is start the conversation on how the development of Renewable Gas could displace dirty fossil fuels, and eventually replace the cleaner-but-still-fossil Natural Gas as well.

It’s clear to me that the near-term and mid-term future for energy in the United Kingdom and the European Union will best be centred on Natural Gas and Renewable Electricity, and now the UK Energy Research Centre has modelled essentially the same scenario. This can become a common narrative amongst all parties – the policy people, the economists, the technologists, the non-governmental groups, as long as some key long-term de-carbonisation and energy security objectives are built into the plan.

The researchers wanted to emphasise from their report that the use of Natural Gas should not be a default option in the case that other strategies fail – they want to see a planned transition to a de-carbonised energy system using Natural Gas by design, as a bridge in that transition. Most of the people in the room found they could largely agree with this. Me, too. My only caveat was that when the researchers spoke about Gas-CCS – Natural Gas-fired power generation with Carbon Capture and Storage attached, my choice would be Gas-CCU – Natural Gas-fired power generation with Carbon Capture and Re-utilisation – carbon recycling – which will eventually lead to much lower emissions gas supply at source.

What follows is a transcription of my poorly-written notes at the meeting, so you cannot accept them as verbatim.

[JW] Thanks to Matt Aylott. Live Tweeting #FutureOfGas. Clearly gas is very very important. It’s never out of the news. The media all want to talk about fracking… If we want to meet the 2 degrees Celsius target of the United Nations Framework Convention on Climate Change, how much can gas be a part of this ? Is Natural Gas a bridge – how long a ride will that gas bridge be ?

[CM] Gas as a bridge ? There is healthy debate about the Natural Gas contribution to climate change [via the carbon dioxide emissions from burning Natural Gas, and also about how much less in emissions there is from burning Natural Gas compared to burning coal]. The IPCC said that “fuel switching” from coal to gas would offer emissions benefits, but some research, notably McJeon et al. (2014) made statements that switching to Natural Gas cannot confer emissions benefits. Until recently, there have not been many disaggregated assessments on gas as a bridge. We have used TIAM-UCL. The world is divided into 16 regions. The “climate module” seeks to constrain the global temperature rise to 2 degrees Celsius. One of the outcomes from our model was that export volumes [from all countries] would be severaly impacted by maintaining the price indexation between oil and gas. [Reading from chart on the screen : exports would peak in 2040s]. Another outcome was that gas consumption is not radically affected by different gas market structures. However, the over indexation to the oil price may destroy gas export markets. Total exports of natural gas are higher under the 2 degrees Celsius scenario compared to the 4 degrees Celsius scenario – particularly LNG [Liquefied Natural Gas]. A global climate deal will support gas exports. There will be a higher gas consumption under a 2 degrees Celsius deal compared to unconstrained scenario [leading to a 4 degrees Celsius global temperature rise]. The results of our modelling indicate that gas acts as a bridge fuel out to 2035 [?] in both absolute and relative terms. There is 15% greater gas consumption in the 2 degrees Celsius global warming scenario than in the 4 degrees Celsius global warming scenario. Part of the reason is that under the 4 degrees Celsius scenario, Compressed Natural Gas vehicles are popular, but a lot less useful under the 2 degrees Celsius scenario [where hydrogen and other fuels are brought into play].

There are multiple caveats on these outcomes. The bridging period is strictly time-limited. Some sectors need to sharply reduce consumption [such as building heating by Natural Gas boilers, which can be achieved by mass insulation projects]. Coal must be curtailed, but coal-for-gas substitution alone is not sufficient. Need a convincing narrative about how coal can be curtailed. In an absence of a global binding climate deal we will get consumption increases in both coal and gas. In the model, gas is offsetting 15% of coal by 2020, and 85% by 2030. With Carbon Capture and Storage (CCS), gas’s role is drastically reduced – after 2025 dropping by 2% a year [of permitted gas use]. Not all regions of the world can use gas as a bridge. [Reading from the chart : with CCS, gas is a strong bridging fuel in the China, EU, India, Japan and South Korea regions, but without CCS, gas is only strong in China. With CCS, gas’s bridging role is good in Australasia, ODA presumably “Offical Development Assistance” countries and USA. Without CCS, gas is good for Africa, Australasia, EU, India, Japan, South Korea, ODA and USA.]

In the UK, despite the current reliance on coal, there is little scope to use it as a transition fuel. Gas is unlikely to be removed from UK energy system by 2050.

[Question from the floor] The logic of gas price indexation with the oil price ?

[CM] If maintain oil indexation, exports will reduce as countries turn more towards indigenous at-home production of gas for their domestic demand. This would not be completely counter-balanced by higher oil and therefore gas prices, which should stimulate more exports.

[Point from the floor] This assumes logical behaviour…

[Question from the floor] [Question about Carbon Capture and Storage (CCS)]

[CM] The model does anticipate more CCS – which permits some extra coal consumption [at the end of the modelling period]. Gas-CCS [gas-fired power generation with CCS attached] is always going to generate less emissions than coal-CCS [coal-fired power generation with CCS attached] – so the model prefers gas-CCS.

So, I turned up for a national Climate Change campaigning and lobbying day some years ago. I had offered to steward at the event. My attire concerned one of those close to the organising team. After all, there were Members of Parliament due to attend, and Gentlemen and Ladies of the Press. “I don’t think it’s quite setting the right tone.” she commented.

Well, I want to know what the right tone is, exactly. And I don’t think anybody else does, either. How do we make change happen ? Really ?

I’ve just received another email missive from The Climate Coalition asking me to Tweet tomorrow about the Carbon Budget.

“As you may remember, back in 2011 we successfully fought for the government to deliver on its climate targets by adopting the Committee on Climate Change’s (CCC) recommendations on the 4th Carbon Budget…”

I mean, that’s a bit of a claim to start with. I very much doubt that anything that the Climate Coalition (or Stop Climate Chaos, as they were known in 2011) did had any bearing on the UK Government’s policy- or decision-making.

“…That decision is currently up for review and we need to make sure the government sticks to the ambition it showed 3 years ago, starting with a Twitter love in this Thursday.”

I beg your pardon ? How can The Climate Coalition make sure the UK Government does anything ? By Tweeting ? OK, so The Climate Coalition is an umbrella organisation of over 40 organisations, ostensibly representing over 11 million people, but it doesn’t have any real political weight, or any serious influence with The Treasury, who are normally the ones resisting the development of the green economy.

“…We’ve heard rumours that this is currently being negotiated in government, with at least some arguing for weaker targets. We don’t know yet which way it’ll go, so David Cameron and Nick Clegg might just need a bit of support from us to make the right decision and stick to our current targets…”

So this is what it’s all about – a show of support for the UK Government !

So, tell me, why should I join in, exactly ? I won’t be having any kind of genuine impact. It’s just a token flag-waving exercise.

I know I’m not setting the right tone, here. I’m challenging the proposals for action from one of the country’s largest collective groups with a clear position about climate change. But that’s because it’s a washout – there is nothing to be gained by responding to this appeal to Tweet.

I mean, if they called for the whole 11 million people to do something actually meaningful, like withdraw their labour for one hour a day, or refuse to use household appliances for 8 hours a week, or all demand a meeting with the fossil fuel producing companies asking them what their plan is to decarbonise the energy supply, then I suppose that might be something worth trying.

But Tweeting ? In support of a Government decision that they ought to make anyway based on the existing Climate Change Law and the science ? Why would they need me to join in with them on that ?

An appeal was issued by David Andrews of the Claverton Energy Research Group, to respond to the Bath Lecture given by Nigel Lawson :-

“Dear All, this group is not meant to be a mere venting of frustration and opinion at what is perceived to be poor policy. So what would be really useful is to have the Lawson spiel with the countering fact interspersed. I can then publish this on the Claverton web site which does get a lot of hits and appears to be quite influential. Can I therefore first thank Ed Sears for making a good effort, but ask him to copy his bits into the Lawson article at the appropriate point. Then circulate it and get others to add in bits. Otherwise these good thoughts will simply be lost in the wind. Dave”

My reply of today :-

“Dear Dave, I don’t have time at the moment to answer all of Nigel Lawson’s layman ruminations, but I have written a few comments here (see below) which begin to give vent to frustration typical of that which his tactics cause in the minds of people who have some acquaintance with the actual science. The sheer volume of his output suggests an attempt to filibuster proper debate rather than foster it. To make life more complicated to those who wish to answer his what I think are absurd notions, he gives no accurate references to his supposed facts or cites any accredited, peer-reviewed documentation that could back up his various emotive generalisations and what appear to be aspersions. Regards, jo.”

This essay is based on the text of a speech given to the Institute for Sustainable Energy and the Environment at the University of Bath.

There is something odd about the global warming debate — or the climate change debate, as we are now expected to call it, since global warming has for the time being come to a halt.

[ joabbess.com : Contrary to what Nigel Lawson is claiming, there is no pause – global warming continues unabated. Of this there can be no doubt. All of the data that has been assessed – and there is a lot of it – confirms the theoretical framework – so it is odd that Nigel Lawson states otherwise, seemingly without any evidence to substantiate his assertion. Nigel Lawson appears to be taking advantage of fluctuations, or short-term wrinkles, in the records of air temperatures close to the Earth, to claim that up is down, dark is light and that truth is in error. Why are temperatures in the atmosphere close to the Earth’s surface, or “surface temperatures”, subject to variability ? Because heat can flow through matter, is the short answer. The longer answer is the interplay between the atmosphere and the oceans, where heat is being transfered between parts of the Earth system under conditions of flows such as the movement of air and water – what we call winds and ocean currents. There are detectable patterns in the flows of air and water – and some are oscillatory, so the temperature (taken at any one time) may appear to wriggle up and down (when viewed over a period of time). Despite these wobbles, the overall trend of temperature over several decades has been reliably detected. Despite Nigel Lawson’s attention to air temperatures, they are probably the least significant in detecting global warming, even though the data shows that baseline air temperatures, averaged over time, are rising. The vast proportion of heat being added to the Earth system is ending up in the oceans :-http://www.skepticalscience.com/global-cooling-intermediate.htm
and the rise in ocean temperatures is consistent :-https://www.skepticalscience.com/cherrypicking-deny-continued-ocean-global-warming.html
which indicates that circulatory patterns of heat exchange in the oceans have less effect on making temperatures fluctuate than the movement of masses of air in the atmosphere. This is exactly what you would expect from the study of basic physics. If you give only a cursory glance at the recent air temperatures at the surface of the Earth, you could think that temperatures have levelled off in the last decade or so, but taking a longer term view easily shows that global warming continues to be significant :-http://data.giss.nasa.gov/gistemp/graphs_v3/
What is truly astonishing about this data is that the signal shows through the noise – that the trend in global warming is easily evident by eye, despite the wavy shakes from natural variability. For Nigel Lawson’s information, the reason why we refer to climate change is to attempt to encompass other evidence in this term besides purely temperature measurements. As the climate changes, rainfall patterns are altering, for example, which is not something that can be expressed in the term global warming. ]

I have never shied away from controversy, nor — for example, as Chancellor — worried about being unpopular if I believed that what I was saying and doing was in the public interest.

But I have never in my life experienced the extremes of personal hostility, vituperation and vilification which I — along with other dissenters, of course — have received for my views on global warming and global warming policies.

For example, according to the Climate Change Secretary, Ed Davey, the global warming dissenters are, without exception, “wilfully ignorant” and in the view of the Prince of Wales we are “headless chickens”. Not that “dissenter” is a term they use. We are regularly referred to as “climate change deniers”, a phrase deliberately designed to echo “Holocaust denier” — as if questioning present policies and forecasts of the future is equivalent to casting malign doubt about a historical fact.

[ joabbess.com : Climate change science is built on observations : all historical facts. Then, as in any valid science, a theoretical framework is applied to the data to check the theory – to make predictions of future change, and to validate them. It is an historical fact that the theoretical framework for global warming has not been falsified. The Earth system is warming – this cannot be denied. It seems to me that Nigel Lawwon usurps the truth with myth and unsubstantiated rumour, casting himself in the role of doubting dissenter, yet denying the evidence of the data. He therefore self-categorises as a denier, by the stance of denial that he takes. His denial is also an historical fact, but calling him a denier is not a value judgement. It is for each person to ascribe for themselves a moral value to the kind of denial he expresses. ]

The heir to the throne and the minister are senior public figures, who watch their language. The abuse I received after appearing on the BBC’s Today programme last February was far less restrained. Both the BBC and I received an orchestrated barrage of complaints to the effect that it was an outrage that I was allowed to discuss the issue on the programme at all. And even the Science and Technology Committee of the House of Commons shamefully joined the chorus of those who seek to suppress debate.

[ joabbess.com : Considering the general apathy of most television viewers, it is therefore quite refreshingly positive that so many people decided to complain about Nigel Lawson being given a platform to express his views about climate change, a subject about which it seems he is unqualified to speak with authority of learning. He may consider the complaints an “orchestrated barrage”. Another interpretation could be that the general mood of the audience ran counter to his contributions, and disagreed with the BBC’s decisiont to permit him to air his contrarian position, to the point of vexation. A parallel example could be the kind of outrage that could be expressed if Nigel Lawson were to deny that the Earth is approximately spherical, that gravity means that things actually move out to space rather than towards the ground, or that water is generally warmer than ice. He should expect opposition to his opinions if he is denying science. ]

In fact, despite having written a thoroughly documented book about global warming more than five years ago, which happily became something of a bestseller, and having founded a think tank on the subject — the Global Warming Policy Foundation — the following year, and despite frequently being invited on Today to discuss economic issues, this was the first time I had ever been asked to discuss climate change. I strongly suspect it will also be the last time.

The BBC received a well-organised deluge of complaints — some of them, inevitably, from those with a vested interest in renewable energy — accusing me, among other things, of being a geriatric retired politician and not a climate scientist, and so wholly unqualified to discuss the issue.

[ joabbess.com : It is a mark of integrity to put you money where your mouth is, not an indicator on insincerity. It is natural to expect people who accept climate change science to be taking action on carbon dioxide emissions, which includes investment in renewable energy. ]

Perhaps, in passing, I should address the frequent accusation from those who violently object to any challenge to any aspect of the prevailing climate change doctrine, that the Global Warming Policy Foundation’s non-disclosure of the names of our donors is proof that we are a thoroughly sinister organisation and a front for the fossil fuel industry.

As I have pointed out on a number of occasions, the Foundation’s Board of Trustees decided, from the outset, that it would neither solicit nor accept any money from the energy industry or from anyone with a significant interest in the energy industry. And to those who are not-regrettably-prepared to accept my word, I would point out that among our trustees are a bishop of the Church of England, a former private secretary to the Queen, and a former head of the Civil Service. Anyone who imagines that we are all engaged in a conspiracy to lie is clearly in an advanced stage of paranoia.

The reason why we do not reveal the names of our donors, who are private citizens of a philanthropic disposition, is in fact pretty obvious. Were we to do so, they, too, would be likely to be subject to the vilification and abuse I mentioned earlier. And that is something which, understandably, they can do without.

That said, I must admit I am strongly tempted to agree that, since I am not a climate scientist, I should from now on remain silent on the subject — on the clear understanding, of course, that everyone else plays by the same rules. No more statements by Ed Davey, or indeed any other politician, including Ed Milliband, Lord Deben and Al Gore. Nothing more from the Prince of Wales, or from Lord Stern. What bliss!

But of course this is not going to happen. Nor should it; for at bottom this is not a scientific issue. That is to say, the issue is not climate change but climate change alarmism, and the hugely damaging policies that are advocated, and in some cases put in place, in its name. And alarmism is a feature not of the physical world, which is what climate scientists study, but of human behaviour; the province, in other words, of economists, historians, sociologists, psychologists and — dare I say it — politicians.

[ joabbess.com : Au contraire, I would say to Nigel Lawson. At root, climate change is very much a scientific issue. Science defines it, describes it and provides evidence for it. Climate change is an epistemological concern, and an ontological challenge. How we know what we know about climate change is by study of a very large number of results from data collection and other kinds of research. The evidence base is massive. The knowledge expressed in climate change science is empirical – based on observations – which is how we are sure that what we know is assured. There is still scope for uncertainty – will the surface temperatures rise by X plus or minus some Y, owing to the dynamic between the atmosphere, the oceans, the ice cover and the land masses ? The results of the IPCC assessments are that we pretty much know what X is, and we have an improved clarity on a range of values for Y. The more science is done, the clearer these numbers emerge. Knowledge increases as more science is done, which is why the IPCC assessments are making firmer conclusions as time passes. Climate change science does not make value judgements on its results. It concludes that sea levels are rising and will continue to rise; that rainfall patterns are changing and will continue to change; that temperatures are rising and will continue to rise under current economic conditions and the levels of fossil fuel use and land use. Science describes the outcomes of these and other climate changes. It is for us as human beings, with humanity in our hearts, to place a meaning on predicted outcomes such as crop and harvest failures, displacement of peoples, unliveable habitats, loss of plant and animal species, extreme weather. You cannot take the human out of the scientist. Of course scientists will experience alarm at the thought of these outcomes, just as the rest of society will do. The people should not be denied the right to feeling alarm. ]

And en passant, the problem for dissenting politicians, and indeed for dissenting climate scientists for that matter, who certainly exist, is that dissent can be career-threatening. The advantage of being geriatric is that my career is behind me: there is nothing left to threaten.

[ joabbess.com : Climate change science is not something you can “dissent” from if you are at all versed in it. For those who question any part of climate change science from inside the community of those who have appropriate knowledge and learning, their position is not one of dissent, but of being unable to assent completely to the conclusions of their peers. They lack a capacity to fully assent to the results of other people’s research because their own research indicates otherwise. As responsible members of the science community, they would then put their research conclusions and the research conclusions of others to the test. There is an integrity in this kind of questioning. It is a valid position, as long as the questions are posed in the language of scientific enquiry, and answered with scientific methods. For example, the Berkeley BEST team had questions about the evidence of global warming and set out to verify or falsify the results of others. Their own research led them to become convinced that their peers had been correct in the their conclusions. This is how science comes to consensus. Nigel Lawson should fund research in the field if he wishes to be taken seriously in denying the current consensus in climate change science. Instead of which, he invests in the publication of what appears to be uncorroborated hearsay and emotive politicking. ]

But to return: the climate changes all the time, in different and unpredictable (certainly unpredicted) ways, and indeed often in different ways in different parts of the world. It always has done and no doubt it always will. The issue is whether that is a cause for alarm — and not just moderate alarm. According to the alarmists it is the greatest threat facing humankind today: far worse than any of the manifold evils we see around the globe which stem from what Pope called “man’s inhumanity to man”.

[ joabbess.com : Nigel Lawson doesn’t need to tell anyone that weather is changeable and that climate changes. They can see it for themselves if they care to study the data. Climate change science has discovered that the current changes in the climate are unprecedented within at least the last 800,000 years. No previous period of rapid climate change in that era has been entirely similar to the changes we are experiencing today. This is definite cause for alarm, high level alarm, and not moderate. If there is a fire, it is natural to sound the alarm. If there is a pandemic, people spread the news. If there is a risk, as human beings, we take collective measures to avoid the threat. This is normal human precautionary behaviour. It is unreasonable for Nigel Lawson to insist that alarm is not an appropriate response to what is patently in the process of happening. ]

Climate change alarmism is a belief system, and needs to be evaluated as such.

[ joabbess.com : Belief in gravity, or thinking that protein is good to eat are also belief systems. Everything we accept as normal and true is part of our own belief system. For example, I believe that Nigel Lawson is misguided and has come to the wrong conclusions. The evidence lies before me. Is my opinion to be disregarded because I have a belief that Nigel Lawson is incorrect ? ]

There is, indeed, an accepted scientific theory which I do not dispute and which, the alarmists claim, justifies their belief and their alarm.

This is the so-called greenhouse effect: the fact that the earth’s atmosphere contains so-called greenhouse gases (of which water vapour is overwhelmingly the most important, but carbon dioxide is another) which, in effect, trap some of the heat we receive from the sun and prevent it from bouncing back into space.

Without the greenhouse effect, the planet would be so cold as to be uninhabitable. But, by burning fossil fuels — coal, oil and gas — we are increasing the amount of carbon dioxide in the atmosphere and thus, other things being equal, increasing the earth’s temperature.

But four questions immediately arise, all of which need to be addressed, coolly and rationally.

First, other things being equal, how much can increased atmospheric CO2 be expected to warm the earth? (This is known to scientists as climate sensitivity, or sometimes the climate sensitivity of carbon.) This is highly uncertain, not least because clouds have an important role to play, and the science of clouds is little understood. Until recently, the majority opinion among climate scientists had been that clouds greatly amplify the basic greenhouse effect. But there is a significant minority, including some of the most eminent climate scientists, who strongly dispute this.

[ joabbess.com : Simple gas chemistry and physics that is at least a century old is evidence that carbon dioxide allows sunlight to pass right through to warm the Earth, which then emits infrared light because it has warmed up. When the infrared radiation is emitted, the Earth cools down. Infrared is partially blocked by carbon dioxide, which absorbs it, then re-radiates it, partially back to the Earth, which warms up again. Eventually, the warming radiation will escape the carbon dioxide blanket, but because of this trapping effect, the net result is for more heat to remain in the atmosphere close to the Earth’s surface than you would expect. This is the main reason why the temperature of the Earth’s surface is warmer than space. As carbon dioxide accumulates in the atmosphere, the warming effect will be enhanced. This is global warming and it is undisputed by the overwhelming majority of scientists. Climate sensitivity, or Equilibrium Climate Sensitivity (ECS) is a calculated measure of the total temperature change that would be experienced (after some time) at the surface of the Earth for a doubling of atmospheric carbon dioxide concentrations compare to the pre-industrial age. The Transient Climate Response (TCR) is a measure of the temperature change that would be experienced in the shorter-term for a doubling of atmospheric carbon dioxide concentrations. The TCR can be easily calculated from basic physics. The shorter-term warming will cause climate change. Some of the changes will act to cool the Earth down from the TCR (negative feedbacks). Some of the changes will act to heat the Earth up from the TCR (positive feedbacks). These are some disagreements about the ECS, such as the net effects from the fertilisation effect of carbon dioxide on plant growth, the net effects of changes in weather and cloud systems, and the net effects of changes in ocean and atmospheric circulation. However, evidence from the deep past (paleoclimatology) is helping to determine the range of temperatures that ECS could be. ]

Second, are other things equal, anyway? We know that, over millennia, the temperature of the earth has varied a great deal, long before the arrival of fossil fuels. To take only the past thousand years, a thousand years ago we were benefiting from the so-called medieval warm period, when temperatures are thought to have been at least as warm, if not warmer, than they are today. And during the Baroque era we were grimly suffering the cold of the so-called Little Ice Age, when the Thames frequently froze in winter and substantial ice fairs were held on it, which have been immortalised in contemporary prints.

[ joabbess.com : The Medieval Warming Period (or Medieval Warm Period) was just a blip compared to the current global warming of the last 150 years. And the Little Ice Age was also a minor anomaly, being pretty much confined to the region of Europe, and some expect could have become the Rather Much Longer Icy Period had it not been for the use of fossil fuels, which warmed Europe up again. Burning coal and other fossil fuels releases carbon that would have originally been in the atmosphere in the form of carbon dioxide millions of years ago, that trees and other plants used to grow. Geological evidence shows that surface temperatures at those times were warmer than today. ]

Third, even if the earth were to warm, so far from this necessarily being a cause for alarm, does it matter? It would, after all, be surprising if the planet were on a happy but precarious temperature knife-edge, from which any change in either direction would be a major disaster. In fact, we know that, if there were to be any future warming (and for the reasons already given, “if” is correct) there would be both benefits and what the economists call disbenefits. I shall discuss later where the balance might lie.

[ joabbess.com : The evidence from the global warming that we have experienced so far since around 1880 is almost universally limiting in terms of the ability of species of animals and plants to survive. There are tiny gems of positive outcomes, compared to a sand pit of negatives. Yes, of course it matters. The mathematics of chaos with strong perturbations to any system do not permit it to coast on a precarious knife-edge for very long. Sooner or later there will be a major alteration, and the potential for some milder probable outcomes will collapse. ]

And fourth, to the extent that there is a problem, what should we, calmly and rationally, do about it?

[ joabbess.com : The most calm and rational thing to do is to compile all the evidence and report on it. Oh yes, we’ve already done that. It’s called the Intergovernmental Panel on Climate Change or IPCC. The concluisons of the compilation of over 100 years of science is that global warming is real, and it’s happening now, and that there is a wide range of evidence for climate change, and indicators that it is a major problem, and that we have caused it, through using fossil fuels and changing how we use land. ]

It is probably best to take the first two questions together.

According to the temperature records kept by the UK Met Office (and other series are much the same), over the past 150 years (that is, from the very beginnings of the Industrial Revolution), mean global temperature has increased by a little under a degree centigrade — according to the Met Office, 0.8ºC. This has happened in fits and starts, which are not fully understood. To begin with, to the extent that anyone noticed it, it was seen as a welcome and natural recovery from the rigours of the Little Ice Age. But the great bulk of it — 0.5ºC out of the 0.8ºC — occurred during the last quarter of the 20th century. It was then that global warming alarmism was born.

[ joabbess.com : Nigel Lawson calls it “alarmism”. I call it empirical science. And there are many scientific explanations for what he calls “fits and starts”, it’s just that they’re written in research papers, so he will probably never read them, going on his lack of attention to research publications in the past. ]

But since then, and wholly contrary to the expectations of the overwhelming majority of climate scientists, who confidently predicted that global warming would not merely continue but would accelerate, given the unprecedented growth of global carbon emissions, as China’s coal-based economy has grown by leaps and bounds, there has been no further warming at all. To be precise, the latest report of the Intergovernmental Panel on Climate Change (IPCC), a deeply flawed body whose non-scientist chairman is a committed climate alarmist, reckons that global warming has latterly been occurring at the rate of — wait for it — 0.05ºC per decade, plus or minus 0.1ºC. Their figures, not mine. In other words, the observed rate of warming is less than the margin of error.

[ joabbess.com : It is not valid for Nigel Lawson to claim that there has been “no further warming at all”. Heat accumulation continues to be documented. Where is Nigel Lawson’s evidence to support his claim that the IPCC is a “deeply flawed body” ? Or is that another one of his entirely unsubstantiated dismissals of science ? Does he just fudge the facts, gloss over the details, pour scorn on scientists, impugn the academies of science, play with semantics, stir up antipathy, wave his hands and the whole history of science suddenly vanishes in a puff of dismissive smoke ? I doubt it ! Nigel Lawson says “the observed rate of warming is less than the margin of error.” This is ridiculous, because temperature is not something that you can add or subtract, like bags of sugar, or baskets of apples, or Pounds Sterling to the Global Warming Policy Foundation’s public relations fund. Two degrees Celsius, or Centigrade, is not twice as warm as one degree Celsius. 30 degrees C doesn’t indicate twice as much heat as 15 degrees C, or require twice as much heating. The range of figures that Nigel Lawson is quoting, minus 0.05 degrees C plus or minus 0.1 degrees C, that is, somewhere between a cooling of 0.05 degrees C and a warming of 0.15 degrees C, is a calculation of temperature trends averaged over the whole Earth’s surface for the last 15 years :-http://www.climatechange2013.org/images/uploads/WGIAR5_WGI-12Doc2b_FinalDraft_Chapter09.pdf (Box 9.2)
It is not surprising that over such a short timescale it might appear that the Earth as experienced a mild cooling effect. In the last 15 years there have been a couple of years far hotter than average, and these spike the calculated trend. For example, 1998 was much hotter than the years before or after it, so if you were just to compare 1998 with 2008, it would look like the Earth is cooling down. But who would be foolish enough to look at just two calendar years of the data record on which to base their argument ? The last 15 years have to be taken in context. In “Climate Change 2013 : The Physical Science Basis”, the IPCC report from Working Group 1, in the Summary for Policymakers, page 5, Section B1, the IPCC write :-http://www.climatechange2013.org/images/report/WG1AR5_ALL_FINAL.pdf
“In addition to robust multi-decadal warming, global mean surface temperature exhibits substantial decadal and interannual variability […] Due to natural variability, trends based on short records are very sensitive to the beginning and end dates and do not in general reflect long-term climate trends. As one example, the rate of warming over the past 15 years (1998–2012; 0.05 [–0.05 to 0.15] °C per decade), which begins with a strong El Niño, is smaller than the rate calculated since 1951 (1951–2012; 0.12 [0.08 to 0.14] °C per decade).” (El Niño is a prominent pattern of winds and ocean currents in the Pacific Ocean with two main states – one that tends to produce a warming effect on the Earth’s surface temperatures, and the other, La Niña, which has a general cooling effect.) ] In other words, in the last fifteen years, the range of rate of change of temperature is calculated to be somewhere between the surface of the planet cooling by 0.05 degrees Centigrade, up to warming by 0.15 degrees Centigrade :-http://data.giss.nasa.gov/gistemp/graphs_v3/Fig.C.gifhttp://www.climate4you.com/GlobalTemperatures.htm#Recent%20global%20satellite%20temperature
However, this calculation of a trend line does not take account of three things. First, in the last decade or so, the variability of individual years could mask a trend, but relative to the last 50 years, everything is clearly hotter on average. Secondly, temperature is not a “discrete” quantity, it is a continuous field of effect, and it is going to have different values depending on location and time. The temperature for any January to December is only going to be an average of averages. If you were to measure the year from March to February instead, the average of averages could look different, because of the natural variability. Thirdly, there are lots of causes for local and regional temperature variability, all concurrent, so it is not until some time after a set of measurements has been taken, and other sets of measurements have been done, that it is possible to determine that a substantial change has taken place. ]

And that margin of error, it must be said, is implausibly small. After all, calculating mean global temperature from the records of weather stations and maritime observations around the world, of varying quality, is a pretty heroic task in the first place. Not to mention the fact that there is a considerable difference between daytime and night-time temperatures. In any event, to produce a figure accurate to hundredths of a degree is palpably absurd.

[ joabbess.com : Nigel Lawson could be said to mislead in his explanation of what “a figure accurate to hundredths of a degree” implies. Temperature is measured on an arbitrarily decided scale. To raise the whole of the Earth surface temperatures by 1 degree Celsius requires a lot of extra trapped energy. The surface temperature of the Earth is increasing by the absorption of energy that amounts roughly to 2 trillion Hiroshima atombic bombs since 1998, or 4 Hiroshimas a second. That is not a small number, although it has to be seen in the full context of the energy flows in and out of the Earth system :-http://www.skepticalscience.com/4-Hiroshima-bombs-per-second-widget-raise-awareness-global-warming.htmlhttp://blogs.discovermagazine.com/imageo/2013/12/03/climate-bomb-redux/#.U2tlfaI-hrQ
Nigel Lawson credits the global temperature monitoring exercise as “heroic”, but then berates its quality. However, climate change scientists do already appreciate that there are differences between daytime and nighttime temperatures – it is called the diurnal range. Besides differences between years, it is known that there are also differences between seasons, and latitudes, and climatic zones. Scientists are not claiming an absolute single value for the temperature of the Earth, accurate to within hundredths of a degree – that’s why they always give a margin of error. What is astonishing from reviews of the data is something that Nigel Lawson has completely missed. Global warming appears to have fractal resolution – that is – at whatever geographical scale you resolve the data, the trend in most cases appears to be similar. If you take a look at some of the websites offering graphs, for example :-http://www.rimfrost.no/http://data.giss.nasa.gov/gistemp/station_data/
the global warming trend is seen to be generally similar when averaged locally, regionally or at the global scale. This is an indicator that the global warming signal is properly being detected, as these trend lines are more or less what you would expect from basic physics and chemistry – the more carbon dioxide in the air, the more heat gets trapped, and the rate of carbon dioxide accumulation in the atmosphere has seen similar trendlines :-http://cdiac.esd.ornl.gov/trends/co2/recent_mauna_loa_co2.html ]

The lessons of the unpredicted 15-year global temperature standstill (or hiatus as the IPCC calls it) are clear. In the first place, the so-called Integrated Assessment Models which the climate science community uses to predict the global temperature increase which is likely to occur over the next 100 years are almost certainly mistaken, in that climate sensitivity is almost certainly significantly less than they once thought, and thus the models exaggerate the likely temperature rise over the next hundred years.

[ joabbess.com : I repeat : there is no pause. The IPCC are not claiming that global warming has stopped, only that there is an apparent “hiatus” in global surface temperature averages. Some scientists have concluded from their work that Climate Sensitivity is less than once feared. However, Climate Sensitivity is calculated for an immediate, once-only doubling of carbon dioxide in the atmosphere, whereas the reality is that carbon dioxide is continuing to build up in the atmosphere, and if emissions continue unabated, there could be a tripling or quadrupling of carbon dioxide concentrations in the atmosphere, which would mean that you would need to multiply the Climate Sensitivity by 1.5 or 2 to arrive at the final top temperature – higher than previously calculated, regardless of whether the expected Climate Sensitivity were to be less than previously calculated. It is therefore illogical for Nigel Lawson to extrapolate from his understanding that Climate Sensitivity is lower than previously calculated to his conclusion that the final level of global warming will be lower than previously calculated. The more carbon dioxide we emit, the worse it will be. ]

But the need for a rethink does not stop there. As the noted climate scientist Professor Judith Curry, chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, recently observed in written testimony to the US Senate:
“Anthropogenic global warming is a proposed theory whose basic mechnism is well understood, but whose magnitude is highly uncertain. The growing evidence that climate models are too sensitive to CO2 has implications for the attribution of late-20th-century warming and projections of 21st-century climate. If the recent warming hiatus is caused by natural variability, then this raises the question as to what extent the warming between 1975 and 2000 can also be explained by natural climate variability.”

[ joabbess.com : The IPCC reports constitute the world’s best attempts to “rethink” Climate Change. Professor Judith Curry, in the quotation given by Nigel Lawson, undervalues a great deal of her colleagues’ work by dismissing their valid attribution of Climate Change to the burning of fossil fuels and the change in land use. ]

It is true that most members of the climate science establishment are reluctant to accept this, and argue that the missing heat has for the time being gone into the (very cold) ocean depths, only to be released later. This is, however, highly conjectural. Assessing the mean global temperature of the ocean depths is — unsurprisingly — even less reliable, by a long way, than the surface temperature record. And in any event most scientists reckon that it will take thousands of years for this “missing heat” to be released to the surface.

[ joabbess.com : That the oceans are warming is not conjecture – it is a statement based on data. The oceans have a far greater capacity for heat retention than the atmosphere, so yes, it will take a long time for heat in the oceans to re-emerge into the atmosphere. However, the processes that directed heat into the oceans rather than the atmosphere in recent years could easily reverse, and in a short space of time the atmosphere could heat up considerably. In making his arguments, Nigel Lawson omits to consider this eventuality, which lowers considerably the value of his conclusions. ]

In short, the CO2 effect on the earth’s temperature is probably less than was previously thought, and other things — that is, natural variability and possibly solar influences — are relatively more significant than has hitherto been assumed.

[ joabbess.com : Nothing about science has changed. The Earth system continues to accumulate heat and respond to that. Carbon dioxide still contributes to the Greenhouse Effect, and extra carbon dioxide in the air will cause further global warming. The Transient Climate Response to carbon dioxide is still apparently linear. The Equilibrium Climate Sensitivity is still calculated to be roughly what it always has been – but that’s only for a doubling of atmospheric carbon dioxide. If more methane is emitted as a result of Arctic warming, for example, or the rate of fossil fuel use increases, then the temperature increase of the Earth’s surface could be more than previously thought. Natural variability and solar changes are all considered in the IPCC reports, and all calculations and models take account of them. However, the obvious possibility presents itself – that the patterns of natural variability as experienced by the Earth during the last 800,000 years are themseles being changed. If Climate Change is happening so quickly as to affect natural variability, then the outcomes could be much more serious than anticipated. ]

But let us assume that the global temperature hiatus does, at some point, come to an end, and a modest degree of global warming resumes. How much does this matter?

The answer must be that it matters very little. There are plainly both advantages and disadvantages from a warmer temperature, and these will vary from region to region depending to some extent on the existing temperature in the region concerned. And it is helpful in this context that the climate scientists believe that the global warming they expect from increased atmospheric CO2 will be greatest in the cold polar regions and least in the warm tropical regions, and will be greater at night than in the day, and greater in winter than in summer. Be that as it may, studies have clearly shown that, overall, the warming that the climate models are now predicting for most of this century (I referred to these models earlier, and will come back to them later) is likely to do more good than harm.

[ joabbess.com : The claim that warming will “overall […] do more good than harm” is erroneous, according to Climate Change Science. ]

…

Global warming orthodoxy is not merely irrational. It is wicked.

[ joabbess.com : My conclusions upon reading this lecture are that the evidence suggests that Nigel Lawson’s position is ill-informed. He should read the IPCC reports and re-consider. ]

A key thing to know about Professor David MacKay is that he likes data. Lots of data. He said so in a public meeting last week, and I watched him draw a careful draft diagram on paper, specifying for a project engineer the kind of data he would like to see on Combined Heat and Power (CHP) with District Heating (DH). There have been a number of complaints about communal heating projects in the UK, but accurate information is often commercially sensitive, so urging the collection and publication of data is the way forward.

MacKay has been working on very large data indeed – with his 2050 Pathways Calculator. Although people may complain, in fact, they do complain, that the baseline assumptions about nuclear power seem designed to give the recommended outcome of more nuclear power, other parts of The Calculator are more realistic, showing that a high level of new, quick-to-build largescale wind power is practically non-negotiable for guaranteeing energy security.

Last year, there were some rumours circulating that MacKay’s work on biomass for The Calculator showed that biomass combustion for electricity generation was a non-starter for lowering net greenhouse gas emissions to the atmosphere. We were told to wait for these results. And wait again. And now it appears (according to Private Eye, see below), that these were suppressed by DECC, engaged as they were with rubberstamping biomass conversions of coal-fired power plants – including Drax.

“Old Sparky” at Private Eye thinks that Professor MacKay will not be permitted to publish this biomass data – but as MacKay said last week, The Calculator is open source, and all volunteers are welcome to take part in its design and development…

Keeping the Lights On
by “Old Sparky”

The company that owns the gigantic Drax power station in Yorkshire is cheekily suing the government for not giving it quite as much subsidy as it would like. But it should be careful : the government is suppressing a publication that would question its right to any subsidy at all.

Drax, built as a coalf-fired plant, is converting its six generating units to burn 15m tonnes of wood a year (see Eye 1325). Amazingly, electricity generated from “biomass” like this qualifies as “renewable energy”. It is thus in line for hefty subsidies and Treasury guarantees – several hundred million pounds a year of electricit billpayers’ money once all six units have been converted.

Having seen the even greater bungs proposed for EDF’s two new nuclear power plants, however, Drax thinks it deserves a similar deal and is suing for precisely that (which is what happens when firms subsidy-farming as their main line of business).

Drax’s greed is unlikely to be rewarded. In the Energy Act passed last year, ministers gave themselves remarkable powers to intervene in the electricity industry, project by project, and to do pretty much whatever takes their fancy.

Meanwhile, the chief scientific adviser [sic] at the Department of Energy and Climate Change (DECC), the upright Professor David MacKay, is coming to the end of his five-year term. For more than a year he has been agitating for DECC to publish his “biomass calculator” which proves it is (in his words) “fantastically easy” to show that burning trees on the scale planned by Drax and other converted coal plants is likely to INCREASE CO2 emissions in the timeframe that matters.

Knowing the rumpus this will cause, DECC suppressed it last summer (Eye, 1348) and continues to do so while several large biomass projects get off the ground. Will the scrupulous professor simply return to academia and publish it anyway ? Perhaps : but don’t bank on it : it is usual for employment contracts to stipulate that the EMPLOYER retains intellectual property rights in ideas developed while “on the job”. Although MacKay did some work on the impact of biomass-burning before becoming chief adviser [sic], the “calculator” dates from his time at DECC.

This is just as well for Drax. But perhaps its owners should take the hint and wind in their necks.

I took some notes from remarks made by Professor David MacKay, the UK Government’s Chief Scientific Advisor, yesterday, 1st May 2014, at an event entitled “How Will We Heat London ?”, held by Max Fordhams as part of the Green Sky Thinking, Open City week. I don’t claim to have recorded his words perfectly, but I hope I’ve captured the gist.

[David MacKay] : [Agreeing with others on the panel – energy] demand reduction is really important. [We have to compensate for the] “rebound effect”, though [where people start spending money on new energy services if they reduce their demand for their current energy services].

Things seem to be under-performing [for example, Combined Heat and Power and District Heating schemes]. It would be great to have data. A need for engineering expertise to get in.

I’m not a Chartered Engineer, but I’m able to talk to engineers. I know a kilowatt from a kilowatt hour [ (Laughter from the room) ]. We’ve [squeezed] a number of engineers into DECC [the Department of Energy and Climate Change].

I’m an advocate of Heat Pumps, but the data [we have received from demonstration projects] didn’t look very good. We hired two engineers and asked them to do the forensic analysis. The heat pumps were fine, but the systems were being wrongly installed or used.

Now we have a Heat Network team in DECC – led by an engineer. We’ve published a Heat Strategy. I got to write the first three pages and included an exergy graph.

[I say to colleagues] please don’t confuse electricity with energy – heat is different. We need not just a green fluffy solution, not just roll out CHP [Combined Heat and Power] [without guidance on design and operation].

Sources of optimism ? Hopefully some of the examples will be available – but they’re not in the shop at the moment.

For example, the SunUp Heat Battery – works by having a series of chambers of Phase Change Materials, about the size of a fridge that you would use to store heat, made by electricity during the day, for use at night, and meet the demand of one home. [Comment from Paul Clegg, Senior Partner at Feilden Clegg Bradley Studios : I first heard about Phase Change Materials back in the 1940s ? 1950s ? And nothing’s come of it yet. ] Why is that a good idea ? Well, if you have a heat pump and a good control system, you can use electricity when it’s cheapest… This is being trialled in 10 homes.

Micro-CHP – [of those already trialled] definitely some are hopeless, with low temperature and low electricity production they are just glorified boilers with a figleaf of power.

Maybe there will be hybrid systems – like the combination of a heat pump and a gas boiler – with suitable controls could lop off peaks of demand (both in power and gas).

We have designed the 2050 Pathways Calculator as a tool in DECC. It was to see how to meet the Carbon Budget. You can use it as an energy security calculator if you want. We have helped China, Korea and others to write their own calculators.

A lot of people think CHP is green and fluffy as it is decentralised, but if you’re using Natural Gas, that’s still a Fossil Fuel. If you want to run CHP on biomass, you will need laaaaaarge amounts of land. You can’t make it all add up with CHP. You would need many Wales’-worth of bioenergy or similar ways to make it work.

Maybe we should carry on using boilers and power with low carbon gas – perhaps with electrolysis [A “yay !” from the audience. Well, me, actually]. Hydrogen – the the 2050 Calculator there is no way to put it back into the beginning of the diagram – but it could provide low carbon heat, industry and transport. At the moment we can only put Hydrogen into Transport [in the 2050 Calculator. If we had staff in DECC to do that… It’s Open Source, so if any of you would like to volunteer…

Plan A of DECC was to convert the UK to using lots of electricity [from nuclear power and other low carbon technologies, to move to a low carbon economy], using heat pumps at the consumer end, but there’s a problem in winter [Bill Watts of Max Fordham had already shown a National Grid or Ofgem chart of electricity demand and gas demand over the year, day by day. Electricity demand (in blue) fluctuates a little, but it pretty regular over the year. Gas demand (in red) however, fluctuates a lot, and is perhaps 6 to 10 times larger in winter than in summer.]

If [you abandon Plan A – “electrification of everything”] and do it the other way, you will need a large amount of Hydrogen, and a large Hydrogen store. Electrolysers are expensive, but we are doing/have done a feasibility study with ITM Power – to show the cost of electrolysers versus the cost of your wind turbines [My comment : but you’re going to need your wind turbines to run your electrolysers with their “spare” or “curtailed” kilowatt hours.]

[David Mackay, in questions from the floor] We can glue together [some elements]. Maybe the coming smart controls will help…can help save a load of energy. PassivSystems – control such things as your return temperature [in your Communal or District Heating]…instead of suing your heat provider [a reference to James Gallagher who has problems with his communal heating system at Parkside SE10], maybe you could use smart controls…

[Question] Isn’t using smart controls like putting a Pirelli tyre on a Ford Cortina ? Legacy of poor CHP/DH systems…

[David MacKay in response to the question of insulation] If insulation were enormously expensve, we wouldn’t have to be so enthusastic about it…We need a well-targeted research programme looking at deep retrofitting, instead of letting it all [heat] out.

[Adrian Gault, Committee on Climate Change] We need an effective Government programme to deliver that. Don’t have it in the Green Deal. We did have it [in the previous programmes of CERT and CESP], but since they were cancelled in favour of the Green Deal, it’s gone off a cliff [levels of insulation installations]. We would like to see an initiative on low cost insulation expanded. The Green Deal is not producing a response.

[Bill Watts, Max Fordham] Agree that energy efficiency won’t run on its own. But it’s difficult to do. Not talking about automatons/automation. Need a lot of pressure on this.

[Adrian Gault] Maybe a street-by-street approach…

[Michael Trousdell, Arup] Maybe a rule like you can’t sell a house unless you’ve had the insulation done…

[Peter Clegg] … We can do heat recovery – scavenging the heat from power stations, but we must also de-carbonise the energy supply – this is a key part of the jigsaw.
